Description
본 발명은 건물 등의 옥상, 외부 등 외부유입수를 차단을 위해 도포되는 도막방수재로서 스틸렌-아크릴 공중합 에멀션이 균일하게 분산되어 있어 방수성은 물론 신축성과 통기성을 부여하여 내구성이 우수한 일액형 도막방수재에 관한 것이다. 또한 본 발명의 도막방수재는 균일한 조성물로 구성되어졌으며, 단일 포장용기를 사용하여 현장시공에 있어서 작업편의성을 특징으로 한다.The present invention relates to a one-component coating waterproofing material having excellent durability by providing styrene-acrylic copolymer emulsion uniformly dispersed and providing waterproofness and breathability as a coating waterproofing material applied to block external inflows such as rooftops and exteriors such as buildings. will be. In addition, the coating film waterproofing material of the present invention is composed of a uniform composition, it is characterized by the ease of work in the field construction using a single packaging container.
일반적으로 콘크리트는 특성상 진동이나 온도변화에 민감하여 균열이 생길 수 있도록 되어진 것이다. 이러한 고유의 특성이 시간이 경과 할수록 우수 및 여러 가지 자연 현상으로 인하여 내구성을 악화시켜 건물의 노후화를 촉진시키고 사용자에게 불편을 가중시킨다. 이러한 것을 방지코져 건물의 옥상, 외부 등 외부유입수를 차단할 목적으로 도막방수재를 사용하고 있다.In general, concrete is susceptible to vibration and temperature changes due to its characteristics, so that cracks may occur. Over time, these inherent properties deteriorate durability due to rainwater and various natural phenomena, which promotes aging of buildings and adds inconvenience to users. To prevent this, coating waterproofing materials are used for the purpose of blocking external inflows such as the rooftop and the exterior of buildings.
종래의 도막방수공법은 우레탄 방수공법, 아스팔트 방수공법, 에폭시수지계 방수공법 등이 있으며 각각의 장단점을 살펴보면 다음과 같다.Conventional coating waterproofing method is a urethane waterproofing method, asphalt waterproofing method, epoxy resin-based waterproofing method, etc. Looking at the advantages and disadvantages of each is as follows.
먼저, 우레탄 방수공법은 신축성이 양호하며 접착성이 우수한 도막방수재이나 습윤상태의 바탕면에 시공할 경우 친유기임으로 접착력 확보가 안되며 공기연행이 안되어 도막자체의 부풀음 현상이 발생됨으로 파단되는 경우가 빈번하고 대기온도에 따라 반응촉매 기능의 혼선으로 양질의 도막을 확보하는데 문제점이 있다.First of all, the urethane waterproofing method has a good elasticity and is excellent in adhesion, and when it is applied to the base surface of the wet state, it is lipophilic and it is not secured because of the adhesiveness. There is a problem in securing a high quality coating film due to crosstalk of the reaction catalyst function depending on the atmospheric temperature.
아스팔트방수공법은 가장 오래된 공법으로 낙후된 건설기술의 한계로 주로 쓰여졌으나, 최근에는 겹침부에서 완벽한 접합이 시트 3~4장은 해야하는 어려움 때문에 매끄럽게 처리가 안되어서 문제점이 생길뿐만 아니고, 자재의 재질이 친유기임으로 이질현상에 의하여 일시적으로 접합은 되나, 온도변화 및 시간이 경과함에 따라 유기성분이 증발하여, 당초의 두께가 감소 되면서, 모세관을 통하여 유입된 외부수가 동절기에 빙결 팽창이 되어 파단이 되고, 이러한 현상이 반복되면서 결국은 누수가 되어, 방수성 상실은 물론이고 보수가 용이하지 못하여 최근에는 사용을 기피하는 추세이다.Asphalt waterproofing method was mainly used as a limitation of construction technology which was the oldest method, but recently, perfect bonding at overlapping parts is not smoothly processed due to the difficulty of 3-4 sheets. Although it is lipophilic, it is temporarily bonded due to heterogeneous phenomena, but as the temperature change and time elapses, the organic component evaporates and the thickness of the original is reduced, and the external water introduced through the capillary tube becomes frozen and swells in the winter. As the phenomenon is repeated, water eventually becomes leaked, and not only the loss of waterproofness, but also the maintenance is not easy, and in recent years, the trend of avoiding use.
에폭시수지계 방수공법은 일시적으로 콘크리트에 도막을 형성할 수 있으나, 역시 촉매를 이용한 공법임으로 대기온도에 따라 양을 조절하여 사용해야 하는 번거로움과 내균열성과 햇빛저항성 결여로 내구성이 떨어지는 담점이 있어 사용이 기피되고 있으며, 또한 기존의 무기질 시멘트 혼입형 탄성도막방수재는 기능성 반응개시제의 재료와 에멀션을 적절히 섞어야하는 번거로움과 도막의 중간에 인장력을 확보하기 위하여 별도의 쉬트를 부착해야하는 불편함이 있어서 일반인이 사용하기 힘들고 번거로운 시공으로 양질의 품질을 확보하기 어려운 문제점이 있다.Epoxy resin-based waterproofing can temporarily form a coating film on concrete, but it is also a method using a catalyst, and it is difficult to use due to the hassle and durability that has to be used by adjusting the amount according to the air temperature and lack of crack resistance and sunlight resistance. In addition, the conventional inorganic cement-incorporated elastic coating waterproofing material has been troubled to properly mix the material and emulsion of the functional reaction initiator and the inconvenience of having to attach a separate sheet to secure the tension in the middle of the coating film. This difficult to use and cumbersome construction is difficult to secure a good quality quality.
상기와 같은 종래의 도막방수공법은 기본적으로 바탕면에 수분함유율이 4%이 내가 되어야 시공이 가능하나, 4%이내의 조건은 우리나라 기후 여건상 일년에 1개월 정도이기 때문에 한계가 있을 뿐만아니고, 대부분 2액형 반응개시제는 사용자가 전문성을 갖추지 않으면 불가하고, 또한 양질의 시공이 되었다 하더라도 시공후 대기온도 및 기타 여건에 따라 품질이 훼손될 위험이 많다.The conventional coating film waterproofing method as described above can be installed only when the moisture content on the base surface is 4% or less, but the condition within 4% is limited because it is about 1 month a year due to the climatic conditions of Korea. Most two-part reaction initiators are impossible without the user's expertise, and even if they are of good quality, there is a high risk of quality deterioration depending on air temperature and other conditions after construction.

본 발명을 상세히 설명하면 다음과 같다.The present invention is described in detail as follows.
본 발명에 따른 일액형 도막방수재는 스티렌단량체와 부틸아크릴레이트를 유화중합하여 스티렌-아크릴 공중합 에멀션을 제조한 후, 상기 스티렌-아크릴 공중합 에멀션에 분산제, 소포제, 억포제를 첨가하여 제조되는 것이다. The one-component coating waterproofing material according to the present invention is prepared by emulsion polymerization of styrene monomer and butyl acrylate to prepare a styrene-acrylic copolymer emulsion, and then adding a dispersant, an antifoaming agent, and an antifoaming agent to the styrene-acrylic copolymer emulsion.
본발명에 따른 일액형 도막방수재의 제조방법은 물, 스티렌단량체, 부틸아크릴게이트, 친유기·무기유화제를 혼합하여 혼합물을 제조하여 유화중합을 하는 제1단계와, 상기 혼합물에 물을 더 첨가하여 공중합을 완성시켜 에멀션을 제조하는 제2단계, 상기 에멀션의 점도 및 물성을 조절하여 완성된 스티렌-아크릴 공중합 에멀션을 제조하는 제3단계, 상기 스티렌-아크릴 공중합 에멀션에 수용성 라텍스, 분산제. 소포제를 첨가하여 도막방수재를 완성시키는 제4단계로 제조된다.Method for producing a one-component coating waterproofing material according to the present invention is a first step of preparing a mixture by mixing water, styrene monomer, butyl acrylic gate, lipophilic and inorganic emulsifiers to perform an emulsion polymerization and copolymerization by further adding water to the mixture A second step of preparing an emulsion to prepare an emulsion, a third step of preparing a completed styrene-acrylic copolymer emulsion by adjusting the viscosity and physical properties of the emulsion, a water-soluble latex in the styrene-acrylic copolymer emulsion, a dispersant. It is prepared in the fourth step of adding a defoaming agent to complete the coating waterproofing material.
각각의 단계를 상세히 설명하면 다음과 같다.Each step will be described in detail as follows.
상기 제1단계는 물 20Kg을 투입후 50~60RPM으로 교반시키면서 스티렌단량체를 20~30Kg을 투입하고 온도를 서서 상승시켜 70~90℃에서 유지되도록 한다.The first step is to add 20 ~ 30Kg of styrene monomer while stirring at 50 ~ 60RPM after adding 20Kg of water to maintain the temperature at 70 ~ 90 ℃ by raising the temperature.
여기에 친유기유화제를 1~2kg를 투입해주고, 연이어 부틸아크릴게이트를 40~60Kg 투입과 동시에 친수기유화제를 2~6Kg 투입하며 혼합물을 제조하고 유화중합을 진행한다.1 ~ 2kg of lipophilic emulsifier is added, 40 ~ 60Kg of butyl acrylates are added subsequently, and 2 ~ 6Kg of hydrophilic emulsifier is added at the same time to prepare a mixture and proceed with emulsion polymerization.
상기 제2단계는 상기 혼합물에 물 10~20Kg 투입하고 믹서온도를 100℃까지 올려서 약 1시간 반응시킨 후, 다시 온도를 140~150℃ 까지 서서히 올려서 15~25분간 공중합반응을 완료시키고, 배합회전을 70~80RPM으로 고정시켜 점도가 550~600 CPS정도의 에멀션을 제조한다.In the second step, 10 ~ 20Kg of water was added to the mixture, and the mixer temperature was raised to 100 ° C. and reacted for about 1 hour. Then, the temperature was gradually raised to 140 ° C. to 150 ° C. to complete the copolymerization reaction for 15 to 25 minutes. Fixed to 70 ~ 80RPM to prepare an emulsion of about 550 ~ 600 CPS viscosity.
상기 제3단계는 상기 에멀션의 온도를 140~150℃에서 4~7분안에 빠르게 25~30℃까지 저온으로 하향시킨다. 저온으로 하향시키면 상기 에멀션의 점도가 1600~1700 CPS까지 상승하게 되며, 이 상태에서 4~7분간 정체시킨 후, 다시 서서히 온도를 110~130℃까지 상승시켜 점도를 조절하고 물성을 변화시킨다.In the third step, the temperature of the emulsion is rapidly lowered from 140 to 150 ° C. to low temperatures of 25 to 30 ° C. in 4 to 7 minutes. When the temperature is lowered to a low temperature, the viscosity of the emulsion is increased to 1600-1700 CPS, and after 4 to 7 minutes in this state, the temperature is gradually raised to 110 to 130 ° C to adjust the viscosity and change physical properties.
상기 제3단계를 2~6회 반복하면 스티렌-아크릴 공중합 에멀션의 물성이 온도에 둔감해져서 신장률이 좋은 스티렌-아크릴 공중합 에멀션을 얻을 수 있다.When the third step is repeated 2 to 6 times, the properties of the styrene-acrylic copolymer emulsion are insensitive to temperature, thereby obtaining a styrene-acrylic copolymer emulsion having good elongation.
상기 제4단계는 상기 스티렌-아크릴 공중합 에멀션을 20~28시간 1차 숙성시킨 다음 믹서를 30~40 RPM으로 교반시키면서 여기에 2차 도막형성 기능재인 수용성 라텍스 15~25Kg과 분산제 2~6Kg, 소포제 0.5~2Kg, 억포제 0.5~5Kg, 물 5~15Kg을 투입혼합 후 20~30시간 2차 숙성을 시켜 본 발명에 따른 일액형 도막방수재를 얻는다.In the fourth step, the styrene-acrylic copolymer emulsion is first aged for 20 to 28 hours and then the mixer is stirred at 30 to 40 RPM, and the water-soluble latex 15-25 Kg and the dispersant 2 to 6 Kg as the secondary coating film-forming material are added thereto. 0.5 ~ 2Kg, 0.5 ~ 5Kg of Suppressant, and 5 ~ 15Kg of water are mixed for 2 to 20 hours after the mixing to obtain a one-component coating waterproofing material according to the present invention.
상기 2차 도막형성 기능재는 수용성 라텍스대신에 부칠고무를 사용할 수 있으나 제조시 별도의 계면활성제를 첨가하여야 하는 번거로움이 있어 신장률이 좋고 수용성으로 친화력이 우수한 수용성 라텍스를 사용하는 것이 바람직하다.The secondary coating film-forming functional material may be used instead of water-soluble latex, but it is preferable to use water-soluble latex having good elongation and good affinity due to the inconvenience of adding a separate surfactant during manufacture.
상기 제4단계에 동결 및 수분급속증발 억제제 1~4Kg을 더 첨가하여 물성을 더욱 향상시킬 수 있다.In the fourth step, the freezing and rapid evaporation inhibitor 1 to 4Kg may be further added to further improve physical properties.
상기 분산제는 본 발명의 도막방수재가 사용시 강알키리의 시멘트와 혼합되므로 시멘트를 분산시키는 작용을 위한 것으로 축합나프탈렌설폰산소다염과 암모니아염등의 모노머(monomer)형 분산제를 사용할 수 있으나 모노머형 분산재는 반응율 이 민감하여 2차 반응율이 적고 시멘트처럼 이온작용이 혼란스러운 물질에는 안정적인 폴리머(polymer)형 분산제를 사용하는 것이 바람직하다.The dispersant is to disperse the cement because the coating waterproofing material of the present invention is mixed with the cement of the strong Alkyri may be used a monomer type dispersant such as condensation naphthalene sulfonate polybasic salt and ammonia salt, but the monomer type dispersant has a reaction rate It is preferable to use a stable polymer type dispersant for the sensitive, low secondary reaction rate and confusing ions such as cement.
상기 폴리머형 분산제는 시멘트를 이완시켜주고 폴리머에 작용기가 없는 폴리카르복실산 소다염 분산재등의 폴르카르복실계 분산제를 사용하는 바람직할 것이다.
상기 소포제는 본 발명에 따른 일액형 도막방수재를 시멘트와 혼합하여 사용시 발생되는 거품을 제거하는 목적으로 변성 실리콘계나 폴리에테르계를 사용할 수 있으나 제품의 장기보존성이 떨어지는 등의 문제점으로 시멘트와 친화력 즉 혼용성이 좋고 2차반응이나 안정성면에서 우수한 광물유계 비이온성 소포제를 사용하는 것이 바람직하다. The polymer type dispersant may be preferable to use a polycarboxylic dispersant such as a polycarboxylic acid soda salt dispersant that relaxes the cement and has no functional group in the polymer.
The antifoaming agent may use a modified silicone or polyether type for the purpose of removing bubbles generated when mixing the one-component coating waterproofing material according to the present invention with cement, but due to problems such as poor long-term storage of the product, affinity and mixing of cement It is preferable to use the mineral oil type nonionic antifoamer which is excellent in the property and excellent in secondary reaction or stability.

상기 억포제는 이동시 흔들림으로 인한 거품발생을 억제하기 위한 것으로 변성 실리콘계와 아마이드계을 들수있으나 고가의 제품이고 아마이드계는 성질이 민감하여 대기온도변화에 산화되어 기능손실이 있을 수 있으므로 본 발명의 스티렌-아크릴 공중합 에멀션과 같이 중성의 에멀션에 안정적이고 경제적으로도 유리한 폴리에테르계 억포제를 사용하는 것이 바람직하다.The suppressor is to suppress the foaming caused by the shaking during movement, but may be modified silicone and amide-based, but expensive products and amide-based styrene is sensitive to the nature of the oxidative change in the air temperature may cause a loss of function styrene- Preference is given to using polyether-based inhibitors which are stable and economically advantageous for neutral emulsions, such as acrylic copolymer emulsions.
상기 동결 및 수분급속증발 억제제로는 에틸렌글리콜, 프로필렌글리콜지방에스테르, 알긴산프로필렌글리콜등이 사용될 수 있으나 에틸렌글리콜은 최근에 환경2차 오염물질로 사용에 문제가 있으며, 프로필렌글리콜지방에스테르는 물에 잘 녹지않는 문제점이 있으며, 알긴산프로필렌글리콜은 점도교란이 일어나고 대기의 온도변화에 따라 물성의 변화가 심한 문제점으로 본 발명에 사용되는 억제제로는 프로필렌글리콜을 사용하는 것이 바람직하다.Ethylene glycol, propylene glycol fatty ester, propylene glycol alginate may be used as the freezing and rapid evaporation inhibitor, but ethylene glycol has recently been used as a secondary environmental pollutant, and propylene glycol fatty ester is well There is a problem that does not dissolve, propylene glycol alginate is a problem that the viscosity disturbance occurs and changes in physical properties in accordance with the temperature change of the atmosphere it is preferable to use propylene glycol as an inhibitor used in the present invention.
본 발명의 일액형 도막방수재를 제조하기 위해서는 온도제어가 가능하고 회전력이 최고 500RPM까지 사용될 수 있는 믹서를 사용하는 것이 바람직할 것이다.In order to manufacture the one-component coating waterproofing material of the present invention, it would be desirable to use a mixer capable of temperature control and a rotational force of up to 500 RPM.
본 발명의 일액형 도막방수제 의 주성분인 스티렌-아크릴 공중합 에멀션의 입자는 0.01㎛정도의 입자크기를 가지는 것이 적합하다. 너무 작으면 통기성이 없어서 기능에 문제가 된다. 또한 유리 전이 온도가 너무 낮으면 끈적거림이 생겨서 내오염성의 주범이 되며, 너무 높으면 신장률이 저하되어 구조물의 거동에 대응이 안된다. 또한, 시공 초기에 도막이 건조되기 전에는 작은 입자들은 콘크리트의 조직에 파고들어감으로 향후에 접착력과 방수성능이 향상되는 효과를 기대할 수 있다. 본 발명에 따른 일액형 도막방수재는 대기에 노출, 비 노출되는 장소 중 철, 비철금속, 아크릴바탕, 나무, 수분이 흐르지 않을 정도의 바탕 콘크리트 등 광범위하게 사용될 수 있다.The particles of the styrene-acrylic copolymer emulsion, which is the main component of the one-component coating waterproofing agent of the present invention, preferably have a particle size of about 0.01 μm. If it is too small, it is not breathable, which is a problem for the function. In addition, if the glass transition temperature is too low, it becomes sticky and becomes the main culprit of fouling resistance. If the glass transition temperature is too high, the elongation rate is lowered, so that it does not correspond to the behavior of the structure. In addition, before the coating film is dried at the beginning of construction, small particles penetrate into the structure of the concrete, so that the effect of improving adhesion and waterproof performance can be expected in the future. The one-component coating waterproofing material according to the present invention can be widely used, such as iron, non-ferrous metals, acrylic base, wood, ground concrete such that moisture does not flow in places exposed to the air and not exposed.
